Application filed April 18, 1914. Serial No. 832,790.

To all whom t'may concern:

Be it known that I, WILLIAM BEALLGRAY, a citizen of the United States, and a resident of Louisville, in the county of J efierson and State of Kentucky, have invented a new and useful Improvement in Pipe- Supportsg My invention is an improvement in pipe supports, and has for its object to'provide'a support for interposition between pipes, such as heating pipes, and the'inslrlating conduit Within which the pipe is laid, for supporting the pipe in such manner that it may move during expansion and contraction withoutany danger of buckling or bending of-the pipe or injury to the conduit, and wherein the arrangement is such that the parts always occupy a definite'position with respect to each other whatever the move ment.

In the drawings :-Figure 1 is a transverse vertical section through the support with the supporting conduit in end View, Fig. 2 is a partial longitudinal vertical section, Fig. 3 is a perspective view of the sup port, Fig. 4 is a similar view of another embodiment of the invention, his a partial longitudinal vertical section, FigJG'is an end View with parts insection of'another embodiment of the invention, and Fig. 7 is a perspective view of a stilt.

In the embodiment of the invention shownin Figs. 1 to 3, the improved support vis shown in connection with a pipe 1,'having an insulating covering 2, and arrange'd Within a conduit 3. The conduit is composed of sections, each section having at one end a radially offset flange 4, for receiving the end of the adjacent section, and theconduit' is provided with internal ribs 5, each of which is provided at spaced intervals with pairs of notches 6, the notches of the ribs registering. The support consists of three elements, namely, a saddle in which the piperests, a cradle for engaging the conduit, and a connecting member arranged between the saddle and the cradle and connecting them in such manner that while they may move longitudinally with respect to each other, they must retain at all times a predetermined relative position with respect to each other. The saddle is in the form of a late .7, hav' ing at each side edge a dependlngfla'nge 8, and provided on its under face between the flanges with a plurality of series of rack teeth 9. The series of rack teeth are separated fronfeach other and the teeth of the series are in'regi'ster'. The plate 7 is provlded on its upper face with a plurality of pairs of chairs, the members of the pairs belng opposite each other and one pair being :the chairs as shownmore' especially in Fig. 3 consists of two parallel spaced walls, which are connectedby a web at their outer edges, ,the walls and web constituting a base 10. and ,the web is'extended upward in a leaf 11. The upper edges of the Wall and the leaf are inclinedas's'hown', and the upper surface of each pair of chairs is formed on an arc,

whose' center is the center of the pipe to be supported." Each of the leaves 11 is provided with a transverse slot 12, near its outer,

of the pocket is provided with a longitudinally extending slot 17 and with a series of teeth 18, on each side of the slot. the teeth of the series registering. The spacing of teeth in the cradle pocket corresponds to the spacing of the teeth of the saddle, and the cradle is provided with laterally extending supporting fingers 19, at each side and at the ends of the sides. The supportingfingers have their under sides rounded as shown in Figs. '2 and 3', except a slight facet at bottom, and the said fingcrs'are adapted to eugage the pockets 6 of the ribs 5, before mentioned', to support the cradle between the ribs and above the bottom of the conduit, said fingers being provided for locking down by groove or by oblique face as dotted in at 19*, Fig. 3. A plurality of toothed rollers 20 is arranged between the saddle and the cradle within the pocket on the large sizes and the teeth of each roller mesh with the adjacent series of teeth 9 and 18 of the saddle and cradle. The saddle is provided with a depending web 21 between the adjacent ends of the rollers, for separating the rollers, and the rollers are of such length that they will fit between the flanges S and Patented'Sept. 8,1914.

' arranged at each end of'the plate. Each of the web, and will move smoothly when the pipe expands or contracts. It is obvious that the web 21 might be omitted,-and that a single roller might be used, of a length to extend from near one web 8 to near the other web, the roller having a series of teeth at each end or continuous teeth.

In Fig. 4, the same saddle is usedyand'the same roller or rollers, but the cradle, is somewhat different from that shown in F igs. 1 to .3, and is supported ina diiferentim'an ne r. The cradle comprises a substantially rectangular frame 22, havinga central dee pending pocket 23, and the cradle is pre vided with a plurality of longitudinal see ries of transverse,teeth;24 on the peeked;

The saddle and the.cradleare connectd by;

the rollers 20, or by a singleroller, as may be desired, and at each end the cradle is provided with an arc-shaped extension ,25, which is adapted to engage overashaft or cylindrical support 26. The under face of each of the extensions 25 is shaped to {it the largest size of'shaft used rather closely-and smoothly as shown in Figs.4 andfi, and the ends of the shafts -or supports are adapted to engage the notches 6 of the supporting ribs 5 of the conduit. 1

The above-described construction is especially adapted for" supporting more than one pipe in a single conduit. It will be obvious that the conduit may be of any desired size and that the shafts or supports 26 will be of a length to extend from one rib of the conduit to the other. With this construction of support, it is not necessary to provide every conduit section with the ribs 5 and the notches 6. Every fourth or fifth conduit section will be a rest'section andewill be.

provided with the ribs and notches as shown in Figs land 2. The intermediate lengths or sections of conduit may be plain internally, only enough rest lengths being inserted to properlysupport the pipe.

In Fig. 6, the cradle consists of a plate 27, having at each-sideedge a depending flange or rib 28. On its under face the plate is provided with four longitudinal series of transverse teeth 29, the series being spaced apart from each other asv shown. ,On its upper face the plate 'is' provided with the chairs 29, having the leaves 30, and the'pipe 31 rests upon the upper ends of .the-.chairs,'-1

and is bound to the chairs by the bands. 31 in the usual manner. supports 32 are arranged in the conduit 33,

the ends of the supports resting in notches:

Shafts or cylindrical saddle register with the teeth of each cradle,

and a single roller or two rollers 20 may be used in each.

In Fig. 7, is shown a stilt for interpo .sition between the pipe to be supported and the chairs to permlt the thickness of the insulat on to be varied abnormally if neces;

'sary; When the saddle is arranged to support a certain character of pipe, having a certain predetermined depth of insulation, and it is desired to support a pipe havi'nga much greater depth of irsulation, the stilt maybe interposed between the saddle and, the pipe, the lugs on stilt looking it to the' chairs, The, stilt as shown, comprises a, plate archedbr curved longitudinally tov fit the cha1rs. j The plate is provided intermediate its ends and-at its opposite sidesswith dependinglugs 38, which are adapted to. fit between the pairs of chair walls at each end of the saddle. The plate is also provided at. each end; with pairs of upstanding lugs 39 and 39 the lugs 39 being at one end and the lugs 39* atv vtheother, to be curved to the, arc of pipe supported. The members of the pairs of lugs areat opposite sides of the plate,'1,and thelu'gs'in conjunction with the chair wall'sare adapted to extend through the insulation into contact, with the outer surface of the pipe.

If desired the; supporting fingers 19 of the cradlemaybeprovided with longitudinal grooves 19 1111 .their ,outer faces .for receiving locking tonguesofcement to hold them 1n the notches elf-the ribs of the conduit, or the said fingers. may have their outer faces inclining inwardly toward the top of the, fingersfor the samepurpose.
